Design, planning and build for Tresillian renovation
Cornish housing stock is brilliant and infuriating in equal measure. We renovate cottages, farmhouses, mid-century homes and post-war estates — opening up layouts, fixing damp, adding light and bringing the property up to a standard worth living in. Every Tresillian project we take on begins with reading the local context — Tresillian is a village east of Truro at the head of the Tresillian River, AONB-designated, with a Conservation Area covering the village core, with a building stock that leans toward traditional cob and granite cottages and modern AONB-sensitive infill.
Tresillian sits in Mid Cornwall — covering TR2 from Truro, Tregony, Ladock outward.

Why Tresillian is its own job.
Cornwall Council's lens on Tresillian is consistent: conservation Area covers the village; AONB across the parish. Riverside ecology and views shape applications on the southern edge. For renovation specifically, parts of Tresillian sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Tresillian drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; Cornwall Council's Local Plan applies tighter tests to isolated rural dwellings here, so design rationale and policy fit need to be set out clearly from the outset. That's why we treat every Tresillian project as a TR2-area job first — not a generic Cornwall job with a postcode bolted on. The traditional cob and granite cottages that dominate Tresillian (and continue out toward Ladock) set the tone for any renovation scheme here.
Planning note
Most Cornish renovations don't need planning — but listed status, curtilage listing, Conservation Area designation and material changes can all change that picture.
What we focus on
Renovations considerations specific to Tresillian.
01
Older Cornish properties are often built with cob, rubble or solid granite — modern insulation strategies that work in cavity walls cause damp problems in solid construction. Breathable build-ups matter.
02
Damp in Cornish cottages is usually a moisture management problem, not a chemical injection problem — fixing the cause is cheaper long term than treating the symptom.
03
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.
04
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.

Tresillian Renovations — local questions answered.
- Can you renovate and extend at the same time?
- Yes, and often it's the right call — the planning, regs and disruption all happen once instead of twice. We design and price it as a single project. In Tresillian specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- Do I need planning permission to renovate internally?
- Usually no — except on listed buildings, where Listed Building Consent is needed for many internal alterations. We confirm the position before any wall comes down.
- How much does a full renovation cost in Cornwall?
- A whole-house renovation typically lands between £1,800 and £3,000 per square metre depending on condition, listed status and finish level. We survey before quoting and don't price by guesswork.
- What about damp and old walls?
- We assess the cause first — usually rising damp myths, blocked vents, hard cement renders trapping moisture, or roofs needing attention. A breathable repair strategy fixes most of it without chemical intervention.
- How long does a renovation take?
- Single rooms in weeks, kitchens in two to three months, whole-house renovations in six to fourteen months depending on size and listed status.
